Fix ARRAY_CONTAINS panic when optional partial-match argument is omitted (#14)

Browse Source 
* Fix ARRAY_CONTAINS panic when partial match arg is omitted

The NoSQL parser always emits a third (nil) argument for the optional
partial-match flag of ARRAY_CONTAINS. The executor checked only
len(arguments) > 2 before type-asserting arguments[2] to
parsers.SelectItem, which panicked on the nil value whenever the query
omitted the partial-match argument (e.g. ARRAY_CONTAINS(c.arr, 2)).

Guard the type assertion with a nil check and add an API test covering
ARRAY_CONTAINS with and without the optional partial-match argument.
